Caramelized Onion and Shiitake Soup with Gruyère–Blue Cheese Toasts

Earthy shiitake mushrooms and pungent cheese toasts give this soup more heartiness than classic French onion soup. For a light main course option, pair with a salad that's lightly dressed so it doesn't overpower the soup.

4. Arrange bread in a single layer on a baking sheet. Top each bread slice with 1 teaspoon Gruyère and 1 teaspoon Gorgonzola. Broil 2 minutes or until cheese melts. Sprinkle chopped thyme over cheese. Ladle about 1 cup soup into each of 6 bowls; top each serving with 2 toasts.
